Powers Process Flowrite II 3-Way Bronze Valve vs SS 316 Full Port Ball Valve: Which Fits Your Job?

A used heavy-duty bronze 3-way mixing control valve and a new stainless steel full port ball valve sit at opposite ends of the industrial valve spectrum. This head-to-head breaks down price, operation, and best use so you can choose with confidence.

Last updated Aug 17, 2026

Choosing between these two valves starts with a question: does the valve need to mix and control flow, or just act as a line shutoff? That distinction separates the Powers Process Flowrite II from the ball valve on the other end of the price range, and it should drive your decision before you look at any other detail.

Quick Verdict

If the job is flow mixing and control, choose the Powers Process Flowrite II. If the job is a simple liquid or gas line, choose the ball valve.

The Powers Process Flowrite II is the winner when the valve has to mix flows and act as a control valve. The ball valve is the winner when you want an uncomplicated valve for a liquid or gas line. It is the practical choice when a straightforward valve is the actual job.

Product Notes

Powers Process Flowrite II Heavy Duty Bronze Control Valve 3-Way Mixing

Powers Process 593WM150STMS46RS Flowrite II Heavy Duty Bronze Control Valve 3-Wa

This heavy-duty bronze valve is the option to choose when the system needs to mix flows rather than simply stop them. The 3-way mixing role and the 593WM150STMS46RS model number point to a control valve with a defined specification, and the heavy-duty bronze body suits service where strength matters. It is listed as used, so it is best for buyers who are comfortable with a used valve and who already know the role it will play. At USD 1,126.98, the listed price reflects the control function and build. The main limitation is the combination of used condition and high price; if the job only requires straightforward shutoff, this is more valve than necessary.

1-1/4 Inch NPT Threaded Full Port Stainless Steel SS 316 Ball Valve

1-1/4" 1.25 in NPT Threaded Full Port Ball Valve Stainless Steel SS 316

At the other end of the spectrum, this new stainless steel ball valve is a compact, manual lever design that is ready for a 1-1/4-inch NPT threaded line. The SS 316 body and ball, PTFE seals, and 1000 WOG water-oil-gas rating make it a corrosion-resistant choice for many liquid and gas applications. The full port construction and 2-piece body make it a practical choice for a manual lever valve. At USD 12.09, it keeps the upfront spend low, which matters if you are equipping multiple lines. The main limitation in this pairing is the size and function gap: it is a 1-1/4-inch manual lever ball valve, while the Powers is a 1-1/2-inch control valve for mixing duty. If your line is 1-1/4-inch and you need simple manual operation, this is the more direct fit.

Final Choice by Use Case

Choose the Powers Process Flowrite II when the application calls for the kind of control this valve is built around. Choose the ball valve for general liquid or gas service, where a straightforward valve is all the system needs.
